Basement waterproofing for London projects

Waterproofing is not a finishing detail. It needs to be considered with the basement structure, site conditions, intended room use and how the system will be accessed and maintained.

Coordinate waterproofing with the structure

Construction joints, service penetrations, drainage routes and the junction between existing and new construction all affect a basement waterproofing brief. These interfaces should be considered before excavation and structural work make later changes more difficult.

Part of a complete basement design-and-build service

Basement Structures provides a complete design-and-build service for new-build and retro-fit basements across London, Greater London and the Home Counties. We work with homeowners, architects and developers to coordinate waterproofing requirements with excavation, temporary works, the permanent structure, building services and fit-out.

The appropriate approach is project-specific. We do not assume that one system or detail is suitable for every property.

New-build and retro-fit projects

In a new-build basement, waterproofing can be coordinated from the outset with the structure and construction sequence. In a retro-fit basement, the existing building, restricted access and interfaces with retained construction also need to be considered.

What to send us

To start a useful conversation, share the property location, available drawings, intended use, project stage and any known history of water ingress or previous basement work.
